To all whom it may concern:

Be it known that we, FRED T. VITHEE, a resident of Springfield, in thecounty of Hampden and State of Massachusetts, and ROBERT WHITE, aresident of Cleveland, in the county of Guyahoga and State of Ohio, bothcitizens of the United States of America, have invented new and usefulImprovements in Take-Ups for Looms, of which the following is aspecification, the same being a divisional part of an application forUnited States Letters Patent filed by us September 28, 1906, andserially numbered 336,547.

Our invention relates to improvements in power looms designed especiallyfor weaving wire cloth, and more particularly to mechanism for taking upor rolling up the cloth as it is woven, and consists essentially ofalternately actuated weighted arms with subsidiary and auxiliary parts,all as hereinafter set forth.

The object of our invention is to provide positive and efficient yetsimple mechanism which acts on the cloth-roll to produce the, constantand necessary tensionon the warp and to roll up the cloth as fast as itis woven.

A further object is to provide such mechanism which can be operatedeither automatically or pedally.

We attain these objects by the mechanism illustrated in the accompanyingdrawings, in which Figure 1 is an end elevation of a 100m embodying ourinvention, certain parts of the loom which are not necessary to a clearunderstanding of said invention being left out, and, Fig. 2, a plan viewof one of the take-up arms and associated parts.

Similar figures refer to similar parts throughout the several views.

A suitable frame is represented at 5 for a warp-beam 6, a vertical shaft7, a driveshaft 8, a shaft 9 in front of said drive-shaft and drivenfrom the latter through the medium of meshing gears 10 and 11, abreastroll 12, a cloth-roll 13, a batten 1 1, and the warp andcloth-take-up mechanism presently to be described, the warp -beam andthe cloth-roll being indicated by dotted lines. The warp-beam shaft isournaled at each end in a bearing-block 16, a bracket 17 being providedat each end of the frame 5 for such bearing-block, and bolts 1818 ineach bracket affording means for the adjustment of the bearing-blocktherein. At 19 is a worm-gear on the warp-beam which meshes with a worm20 on the shaft 7.

21. represents a pegwheel on the shaft 7 which peg-wheel is governed bysuitable escapement letoff mechanism not herein shown. The gear 10 istight on the shaft 8 and the gear 11 tight 0n the shaft 9. Thedrive-shaft 8 is mounted in the lower part of the frame 5, in advance ofand parallel with the warp-beam, and has power trans mitted thereto inany suitable manner and from any suitable source. The breast-roll 12 andthe cloth-roll 13 respectively guide and receive the cloth as it iswoven, and their respective shafts 22 and 23 are mounted in the frame.The batten 14 is mounted to swing on the frame, a bolt 24 affordingmeans for vertical adjustment, and a notched rest 25 and its supportingbolts 26 affording means for horizontal adjustment, these members beingthe same at both ends of the loom. The slay is represented at 27 and thereed at 28.

The slay 27 is actuated by a sam 29 011 the drive-shaft 8 and a spring30, through the medium of pivotally-connected arms 31 and 32 generallyarranged in pairs, the former being mounted on a suitably supportedrockshaft 33 and the latter being pivoted as at 341 to the slay. The cam29 acts on a roller (not shown) carried between the arms 31. The springhas one end attached to one of the arms 31 and the other connected byturnbuckle members with a hook 35 in the floor. Two springs 30 and theirconnections are usually employed. *iThe warp-wires 36 pass from thewarpbeam 6, through the heddles indicated by the dotted lines 37 andthrough the reed 28, over the breast-roll 12 to the cloth-roll 13.-Little more of the shedding mechanism appears except the two treadles 38which operate the heddles and are themselves operated by cams on theshaft 9, a portion of one of such cams being seen at 39.

WVhile the parts above pointed out may be generally old and well-known,an understanding thereof is desirable not to say nec essary in order tofully comprehend the new features, with some of which latter such partsenter into quite close combination as will be seen from the followingdescription of said features.

45 on the shaft 9 below As already intimated, the take-up not only 7wheel 40 on each end of the cloth-roll shaft 23, a lever or arm 41mounted on said shaft.

in operative relation with each ratchet-wheel and carrying a weight 42at the end opposite the shaft, a pawl 43 pivoted to each arm at 44 andarranged to engage the teeth on the associated ratchet-wheel in front,and a cam each arm. The front terminals of the arms 41 are preferablyforked, as shown in Fig. 2, and each of said arms is provided with aroller 46 adapted to bear on the cam 45 below.

The arms 41 are oscillated alternately through the medium of the cams 45and contacting rollers 46, one arm at each revolution of the drive-shaft8 since the gears 10 and 11, on the shafts 8 and 9, respectively, are astwo to one, that is, the gear 10 makes two revolutions to one of thegear 11, and as such arm oscillates its pawl 48 rotates the associatedratchet-wheel 40 provided the movement of the arm is sufficient toenable said pawl to advance a tooth. In this way the shaft 23 is rotatedto wind up the cloth on the roll. 13 and to draw the warp from the beam.Except at the instant of being raised by the cams 45 the weight of theloaded arms 41 comes on the roll 13 and the warp-wires 36 because of theengagement of the ratchetwheels 40 by the pawls 43, therefore thedesired tension is always maintained on said wires.

By adding to the take-up mechanism described above the foot-power deviceshown in-Fig. 1,- the take-up can be operated pedally. This deviceconsists of a treadle 47 having its rear end pivoted at 48 to theadjacent end of'the frame 5, a pawl 49 pivoted at 50 to said treadle andpressed by a spring 51 into engagement at the back of and with theratchet-wheel 40 with which said device is associated, said spring beingalso attached to the treadle, and a spring 52 between the floor and thebottom of the treadle. 53 extending outward from the end of frame abovethe free terminal of the treadle 47 limits the upward movement of saidtreadle.

A loom is usually provided with only one A pip root pewr' device,although there might be two for the sake of convenience, one at each endor saidloo m, but in the event that there were two both would not beused at the same time. The device is to be employed when .for any reasonthe cams 45 are not in operation, and it works in conjunction with theweighted arms 41 and the pawls 43, or with one of such arms and its pawlwhen the other arm happens to rest on its cam, the

arm or arms furnishing the tension .for the cloth-roll or for" the warpand the treadle 47 with the pawl 49 causing said cloth-roll to berotated each time said treadle is depressed against the resiliency ofthe spring 52. As the treadle is lifted by the spring 52, after beingdepressed by the foot of the operator, the pawl or pawls of the activearm or arms reengage the teeth on one or both ratchet-wheels 40 and thusnot only prevent the cloth-roll from turning backward but place the sameunder tension.

The weights 42 are arranged to slide on the arms 41 so that they can beeasily adusted thereon to vary the amount of tension exerted by saidarms on the ratchetwheels 40, and a bolt 54 is provided for each weightwith which to tightly secure the same to the arm upon which it ismounted, after adjustment.

What we claim as our invention, and de sire to secure by Letters Patent,is

The combination, in a loom, with the cloth-roll shaft and aratchet-wheel there- ,on, and a weighted arm mounted on said shaft andprovided with a pawl arranged to engage said ratchet-wheel, of apivotallymounted upwardly spring-pressed treadle provided with aspring-pressed pawl also arranged to engage the ratchet-wheel, wherebythe cloth-roll shaft may be intermittently rotated by means of the footof the operator, the pawl on said weighted arm serving as a detent atsuch time.
